Dual Use - outdoor gas grill/convention oven kit

ABSTRACT

An example of what is new or different with my invention is the use of the shield that I created to guide heat flow (convection), to a measured perimeter around the edges of the grate. Avoiding conduction heat that could bum or sear baked foods is accomplished by using the elevated wire racks. The lid is the oven and the temperature inside the oven is monitored by a thermometer outside the oven.

BACKGROUND OF THE INFORMATION

[0004] The common use of an outside propane gas grill is to use radiantheat to grill foods. The amount of heat that is used in the cookingprocess is determined by heat knobs of the gas grill that change theamount of gas supply. Now, with my invention, this same gas grill can beutilized into a new dimension, a convection heat oven that bakes androasts like a regular kitchen oven.

BRIEF SUMMARY OF THE INVENTION

[0005] This invention uses the lid of the gas grill itself to hold inthe regulated convection heat. Also, one side of the lid is the locationfor the thermometer and heat tube.

[0006] A shield made of two pieces of aluminum lays on the grate whichpermits a calculated amount of open space around the perimeter of theshield. A stainless steel wire rack with legs is elevated two andone-half inches above the shield. The amount of heat entering the lid iscontrolled by the openings around the shield and the gas control knobsof the gas grill. The accurate thermometer reading assures perfectresults.

DETAILED DESCRIPTION OF THE INVENTION

[0013] This invention is a kit that contains everything that is requiredto convert an outside propane gas grill into a convection oven and backto a grill again in seconds. The kit contains two sheets of aluminum(about 4 mils), 10″ by 30″ rolled as a cylinder for shipping (thealuminum is the same weight that roofers use to make roof valleys).These aluminum sheets are used as a shield that lay over the existinggrate. The kit contains two stainless steel wire racks 9″×10″ with legsor bends to elevate the racks 2½″ over the shield. The kit also containsan accurate oven thermometer with numbers readable outside the lid forthe temperature inside the oven. A tube of sealant is provided to securethe installation of the thermometer.

[0014] Everything will fit in a shipping box 11×11×5″ high, includinginstructions and recipies.

[0015] This kit can accommodate any outside gas grill with a grate thatmeasures as large as 32 inches or as small as 22 inches. This is aside-to-side measurement (the longest part). This kit will fit justabout every manufactured propane gas grill. Most gas grill grates areabout 26 to 28 inches and about 15 inches from front to back. Tocustomize your gas grill to a convection oven, the process is easy. Thetwo aluminum shield pieces must be 3 inches shorter than the existinggrill grate. The shields are made shorter by folding with any straightedge (a ruler or kitchen counter, etc.).

[0016] They must not be cut because the folds add support. As anexample, if a 27 inch long grate measurement is used, the shield must befolded so that it becomes 24 inches long. More support is obtained byfolding three inches from each end, instead of only one end.

[0017] The two pieces of the aluminum shield should be placedoverlapping over the existing grate so that the existing grate isexposed three-quarters of an inch on the front side and three-quartersof an inch on the back side and, because the shields are already folded,each end side will be exposed one and one-half inches. This importantshield is now customized for your propane gas grill.

[0018] The two wire racks are placed on the surface of the shields inthe center of the grill.

[0019] If the gas grill has a warming rack inside the lid, it must beremoved while the oven is in use. The top hole for the warming rack canbe utilized for the thermometer or a new one-quarter inch hole about 6inches from the top of the lid can be used. The sealant should be usedfrom inside the lid to secure the thermometer and the heat tube.

[0020] When the lid is closed the result is a convection oven.

1. What I claim as my invention, is making a convention oven for bakingand roasting, from an existing propane gas grill with a lid that opensand closes: This invention does not replace the original use of thepropane gas grill; instead, it adds a new dimension. The back-and-forthconversion of grill or oven, when needed, is easy and fast.
